This tooth,- belongs to this jaw, and this jaw,- belongs to a crabeater seal.
If you think that it’s built to crush crabs, you’re wrong. The seal doesn’t eat crabs at all. Instead, crabeater seals mostly feast on tiny Antarctic krill. You see, these complex interlocking cusps act like a filter. First, the seal takes in a mouthful of seawater, and then it closes its jaws and pushes the water out. So its teeth are like natural strainers for trapping krill.
But how about the robust front teeth? Well,- they’re for catching penguins.
